If you wind up going 7mm-08, I would AI it. The benefits of AI don't justufy the expense to having it done on a factory tube, but if you've got to have anew barrel chambered anyway, it doesn't cost any more. An extra 50-75fps and no case trimming are nice pluses. Factory 7mm-08 ammunition will likely meet or exceed velocity in a tight chambered custom tube, with no perceptible difference in accuracy. That's the way it works in my 7mm-08AI....
